The AUD2HTX is a digital module that provides a bridge between
the Audio Subsystem and the HDMI RTX Subsystem. This
module includes intermediate storage to queue SDMA transactions
prior to being synchronized and passed to the HDMI
RTX Subsystem over the Audio Link.

AUD2HTX works as the cpu dai in HDMI audio sound card.
